I just read on an old post in 2011 here that using lime juice to soften kale would work to make it more "palatable." I don't need to soften kale, but I WOULD LOVE to soften broccoli. I looked online to see if recipes do this and they do use lemon juice to marinate but always with salts and oils, which I don't want to do. I don't want it to be too acidic/bitter tasting which without the oil seems like a possibility....
